A Novel Testing Method for Narrowband Synthetic Aperture Radar (SAR) Imaging Algorithm

Imaging algorithms are the key factors of the performances of the synthetic aperture radar (SAR) imaging. Most existing methods usually need to utilize field environment and data, which dramatically reduces the effectiveness of the software testing. This paper presents a novel testing method for narrow-band SAR imaging algorithms, which is consisted of four parts: system parameter verification, echo data simulation, algorithm simulation and real data verification, evaluations of imaging results. This scheme has fully validated the correctness and feasibility of imaging algorithms. Also, this approach greatly improves the validity of the testing work. Finally, the correctness and effectiveness of the proposed method are verified by simulation experiments and real data results.
